A normal +reviewed CAO installation may opt in by installing the receipt-owned +`.squad/cao-evidence-provider.json` and its pinned Node runtime closure. Without a +descriptor, Squad does not collect or restore CAO evidence and leaves the native +research envelope unchanged. + +The narrow descriptor uses schema `squad-evidence-provider/v1`, kind +`cao-farm-v1`, fixed entry +`.squad/cao-evidence-runtime/activity/squad-wave-evidence.mjs`, and +`runtime_files`: SHA-256 hashes keyed by the complete repository-relative paths: +the three `activity/{squad-wave-evidence,squad-farm,authentication}.mjs` files +and `.github/workflows/shared/{policy,setup-github-apps}.mjs`, all beneath +`.squad/cao-evidence-runtime/`. No arbitrary commands, URLs, runtime package +installation, issue-selected repositories, floating references or PR-head code +are supported. Descriptor, runtime and policy come only from the immutable +executing workflow checkout. `SQUAD_WORKFLOW_SHA` identifies that revision; +`GITHUB_SHA` is not a substitute. + +The trusted pre-agent gate collects a complete run-bound bundle into +`/tmp/gh-aw/agent/cao-farm/`. Its `manifest.json` uses +`cao-squad-wave-evidence/v1` and binds the control repository, workflow revision, +policy/enrollment SHA-256 digests, issue, run/attempt, capture/expiry times, +repository revisions and document hashes. `farm/evidence.json` and every other +declared document must be present, regular, hash-matching and bounded. Missing, +partial, tampered, future or expired evidence fails closed. Maximum age is +24 hours, with expiry exactly 24 hours after capture; maximum bundle size is +8 MiB and 256 files. The closed document set is `farm/INDEX.md`, +`farm/evidence.json`, and `farm/{owner}/{repo}/SNAPSHOT.md` for every enrolled +repository. Policy is `.github/workflows/cao.json`: the policy digest hashes its +raw bytes, and enrollment hashes `JSON.stringify(policy['control-plane'].scope)`. + +Before the agent starts, Squad retains that verified bundle as the control +repository's Actions artifact +`squad-cao-evidence--` (one-day retention unless gh-aw's +`vars.GH_AW_DEFAULT_ARTIFACT_RETENTION_DAYS` overrides it; the 24-hour freshness +bound still applies). The trusted publication +gate restores and validates this immutable copy before any successful safe +output. The deterministic research writer validates it again, adds a run link +and structured `evidence` provenance, and updates the native research comment. +The model cannot select the artifact or author provenance. + +The six modes `triage`, `triage revise`, `plan`, `plan revise`, `plan program`, +and `plan program revise` restore only the newest bot-authored research +artifact's referenced wave, validate it against current trusted enrollment, +and keep that lineage. If unavailable or stale, use ordinary `/squad research` +again. Committed install-time `farm/` evidence remains a historical bootstrap +baseline with unchanged receipt ownership, Cast and bootstrap validation. +Sampled issues/PRs describe capture-time observations, not an atomic snapshot. + +Credentials are step-local to collection, never forwarded to the agent. +**Native v1 supports App authentication only.** Collection requires +`vars.GH_AW_GITHUB_AUTH_MODE=app`, `vars.GH_AW_GITHUB_READ_APP_ID` and +`secrets.GH_AW_GITHUB_READ_APP_PRIVATE_KEY`, scoped to the collect step. +Other authentication modes, including PAT and workflow-token-only collection, +fail explicitly as unsupported in v1 before executing the runtime. Restore and +publication validation receive no App credentials. Azure Key +Vault credentials do not automatically become Actions secrets. If CAO Actions +read authentication is absent, this implementation fails rather than silently +asking for duplicate secrets or changing deployment/authentication settings. + +This adds no schedules, dispatch chains, target-repository writes, live +promotion, review bypasses, cast changes or attribution exceptions. Actions +artifact access follows control-repository visibility; CAO must reject visibility +leaks before collection. Hosted two-wave acceptance and live deployment remain +separate approval steps. + +Collection runs the hash-checked runtime with no arguments and the immutable +checkout as cwd. Restored bundles use `--validate-bundle` and +`SQUAD_EVIDENCE_BUNDLE`; their recorded run/attempt and workflow revision stay +bound to the research wave, not the downstream command's new run. The runtime +receives `GITHUB_REPOSITORY`, `SQUAD_WORKFLOW_SHA`, `GITHUB_RUN_ID`, +`GITHUB_RUN_ATTEMPT`, and `SQUAD_ISSUE_NUMBER`. No event-head SHA substitutes for +the executing revision. diff --git a/workflows/aw.yml b/workflows/aw.yml index 9889796e9..2b851ba61 100644 --- a/workflows/aw.yml +++ b/workflows/aw.yml @@ -35,6 +35,8 @@ resources: destination: .github/workflows/shared/squad-install-verifier.mjs - source: shared/squad-command-contract.mjs destination: .github/workflows/shared/squad-command-contract.mjs + - source: shared/squad-evidence-provider.mjs + destination: .github/workflows/shared/squad-evidence-provider.mjs - source: shared/squad-cast-validator.mjs destination: .github/workflows/shared/squad-cast-validator.mjs - source: shared/squad-bootstrap-validator.mjs diff --git a/workflows/package/squad-bootstrap.md b/workflows/package/squad-bootstrap.md index efcc6e251..cec5d6258 100644 --- a/workflows/package/squad-bootstrap.md +++ b/workflows/package/squad-bootstrap.md @@ -153,7 +153,7 @@ pre-agent-steps: node --check "$path" >/dev/null } # BEGIN GENERATED RESOURCE DIGESTS - check_hash "$install_verifier" "a8b8fedd8b2804a061c367f6c67113979aa9d792526e8d052a2f01f697bf3642" + check_hash "$install_verifier" "d12cf4de38e716dd6d0bbb03fda22675477a4559573d3a8601b8f5b2f88f544e" check_hash "$cast_validator" "15f0d47917d269b5b967dc2a782a0eb761c39af7a92ddb64fed687a427070760" check_hash "$bootstrap_validator" "d552d041f006249bfaa67b10a75877f813796b7698c718ac7eb7cf16f3a72e31" # END GENERATED RESOURCE DIGESTS diff --git a/workflows/package/squad-deps-worker.md b/workflows/package/squad-deps-worker.md index 19c056077..25a4dc758 100644 --- a/workflows/package/squad-deps-worker.md +++ b/workflows/package/squad-deps-worker.md @@ -10,6 +10,8 @@ safe-outputs: needs: safe_outputs if: needs.safe_outputs.result == 'success' permissions: + actions: read + contents: read issues: write pull-requests: write max: 1 @@ -20,13 +22,47 @@ safe-outputs: required: true type: string steps: + - name: Checkout immutable research writer + uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 + with: + ref: ${{ github.workflow_sha }} + persist-credentials: false + path: .squad-evidence-trusted-base + - name: Determine installed evidence provider + id: research-evidence-required + uses: actions/github-script@3a2844b7e9c422d3c10d287c895573f7108da1b3 + with: + script: | + const { join } = require('node:path'); + const { pathToFileURL } = require('node:url'); + const root = join(process.env.GITHUB_WORKSPACE, '.squad-evidence-trusted-base'); + const evidence = await import(pathToFileURL(join(root, + '.github/workflows/shared/squad-evidence-provider.mjs')).href); + core.setOutput('enabled', Boolean(evidence.readProvider(root))); + - name: Restore immutable research evidence + if: steps.research-evidence-required.outputs.enabled == 'true' + uses: actions/download-artifact@v8.0.1 + with: + name: squad-cao-evidence-${{ github.run_id }}-${{ github.run_attempt }} + path: /tmp/squad-writer-evidence - name: Upsert Squad research artifact uses: actions/github-script@v9 env: ISSUE_NUMBER: ${{ github.event.issue.number || github.event.pull_request.number || github.event.inputs.issue_number }} + SQUAD_ISSUE_NUMBER: ${{ github.event.inputs.issue_number || github.event.issue.number || github.event.pull_request.number }} + SQUAD_WORKFLOW_SHA: ${{ github.workflow_sha }} with: script: | const { readFileSync } = await import("node:fs"); + const { join } = await import("node:path"); + const { pathToFileURL } = await import("node:url"); + const root = join(process.env.GITHUB_WORKSPACE, '.squad-evidence-trusted-base'); + const evidence = await import(pathToFileURL(join(root, + '.github/workflows/shared/squad-evidence-provider.mjs')).href); + const wave = evidence.readProvider(root) + ?
